FCST CHALLENGE IS POTENTIAL FOR SIGNIFICANT SNOWSTORM ACRS
CENTRAL/SOUTHERN ZNS.

.SYNOPSIS...
COMPLEX UPPER AIR PATTERN CONTS ACRS EASTERN 1/2 OF THE UNITED
STATES WITH SEVERAL EMBEDDED STRONG S/W'S OVER THE CENTRAL/NORTHERN
PLAINS. WATER VAPOR THIS MORNING SHOWS TWO DISTINCT S/W'S WITH ONE
ACRS SOUTHERN IOWA AND ANOTHER OVER NORTHERN MN ATTM...THIS ONE WL
HELP TO DIG MID/UPPER LVL TROF ACRS EASTERN CONUS. OVERALL...MODELS
INITIALIZED VERY WELL WITH THESE FEATURES AND ASSOCIATED 25H DUAL
JET STRUCTURE. FEEL 150KT JET ASSOCIATED WITH SECOND S/W OVER
NORTHERN PLAINS WL HELP DIG TROF OVER THE OHIO VALLEY AND SOUTHERN
MID ATLANTIC STATE TONIGHT...AS FIRST 5H VORT EJECTS ACRS THE MID
ATLANTIC/SNE TODAY/THIS EVENING. NOTE...WATER VAPOR ATTM SHOWS
LIMITED MID/UPPER LVL MOISTURE ASSOCIATED WITH SYSTEM AS CONFLUENT
FLOW ACRS THE GULF COAST STATES IS LIMITING THE MOISTURE ADVECTION
INTO THE SYSTEM...BUT THIS WL CHANGE AS SYSTEM APPROACHES EASTERN
SEABOARD.

SFC ANALYSIS PLACES 1032MB HIGH PRES ACRS OUR NORTHERN FA WITH WEAK
SFC LOW OVER EASTERN KY ATTM. VERY COLD TEMPS CONT WITH MANY PLACES
BTWN -10 AND -25F THIS MORNING AND SFC DWPTS BTWN -20 AND -30F. IT
WL TAKE SOME TIME TO MOISTEN THE ATMOSPHERE UP THIS AFTN/EVENING.
OTHERWISE...SFC OBS ACRS CENTRAL/NORTHERN PLAINS INDICATE 20:1 TO
30:1 SNOW RATIO WITH UPCOMING SYSTEM BASED ON QPF FOR ASOS AND
SNINCR. FEEL OUR RATIO FOR UPCOMING SYSTEM WL BE NEAR 30:1...WHICH
WL LEAD TO A BIG FLUFF FACTOR.

CROSS-SECTION FROM NORTH TO SOUTH ACRS OUR FA SHOWS AREA OF VERY
STRONG 7H FG...AREA OF NEGATIVE EPV...PLENTY OF OMEGA NEAR 7H...AND
LOTS OF MOISTURE THROUGH 5H...WHICH WL HELP TO ENHANCE A BAND OF
MODERATE SNOW ACRS CENTRAL AND SOUTHERN VT BTWN 00Z SUN TO 06Z SUN.

WINDSOR COUNTIES AND MENTION 8-14 INCHES. FOR THE NEXT TIER OF
COUNTIES WL ISSUE WARNING AND MENTION 6-10 INCHES WITH AN ADVISORY
FURTHER NORTH FOR PARTS OF THE DACKS AND MOST OF CENTRAL VT
INCLUDING CHITTENDEN COUNTY VT WITH 3 TO 6 INCHES POSSIBLE BY SUNDAY
AFTN.

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE BURLINGTON VT
1059 PM EST FRI JAN 21 2005

.SHORT TERM...
OVERALL GOING FORECAST FOR TONIGHT LOOKS GOOD AND NO CHANGES NEEDED
AT THE MOMENT.  VERY COLD TEMPERATURES CURRENTLY EXIST OVER THE
ENTIRE AREA AND WILL EASILY REACH FORECAST LOWS. WINDS ARE LIGHT AND
VARIABLE WITH SOME SORT OF NORTHERLY COMPONENT...WHICH HAS ALLOWED
FOR LAKE EFFECT CLOUDS/VERY LIGHT SNOW TO CONTINUE OVER THE SOUTHERN
PORTIONS OF LAKE CHAMPLAIN.  THIS SHOULD CONTINUE THROUGH THE
NIGHT.  QUESTION WILL BE NORTHERN EXTENSION OF HEAVIER PRECIPITATION
AS NEW ETA SHOWING SOLID AREA OF FRONTOGENESIS AROUND 700 MB TO SET
UP OVER SOUTH CENTRAL VERMONT.  PLUS DEFORMATION ZONES TO EXIST OVER
THIS AREA SUNDAY MORNING TO KEEP SOME SNOW GOING.  ALL OF THIS
SUGGEST AN INCREASING POTENTIAL FOR HIGHER SNOW AMOUNTS THAN
CURRENTLY IS FORECAST.  LOTS OF DRY AIR TO OVERCOME HOWEVER AND
WITHOUT EXAMINATION OF GFS...NOT WILLING TO JUMP INTO
WATCHES/WARNINGS/ADVISORIES.  HAVE ISSUED A SPECIAL WEATHER
STATEMENT TO INDICATE POTENTIAL FOR ACCUMULATING SNOWS MAY BE
SHIFTING NORTHWARD INTO THE FORECAST AREA.  STILL LOOKING LIKE BRUNT
OF HEAVIEST SNOWS/BLIZZARD CONDITIONS WILL BE ACROSS SOUTHEAST NEW
YORK AND SOUTHERN NEW ENGLAND.

.PREVIOUS DISCUSSION FROM 331 PM...
COORD WITH ALY...THANX FOR THE CALL. NO HEADLINES ANTICIPATED AT THIS
PT FOR ANY WEEKEND SN THIS FAR NORTH.

.SYNOPSIS...
HI PRESS TO BUILD DOWN ACRS THE FA TONITE. STORM SYS TO MOVE ACRS THE
MID-ATLANTIC REGION ON SAT...THEN TO THE SOUTH OF SRN NEW ENG ON SAT
NITE. ANOTHER HI PRESS RIDGE TO BUILD ACRS THE FA ON SUN AND SUN
NITE. UPR TROF TO MOVE ACRS THE GREAT LKS REGION ON SAT AND THE FA ON
SAT NITE.

.SHORT TERM (THROUGH SUN NITE)...
H85 CAA TO TAKE PLACE ACRS THE FA FOR MUCH OF TONITE AND ON SAT NITE
THRU SUN NITE...WITH WK WAA ON SAT. SOME LOW-LVL MSTR ADVECTION TO
TAKE PLACE ACRS THE FA LATE ON SUN NITE. BEST LOW-LVL FGEN AND MSTR
ADVECTION TO TAKE PLACE MOSTLY TO THE SOUTH OF THE FA OVER THE
WEEKEND. LOW-LVL MSTR TO RETURN ACRS THE FA ON SAT AFTERNOON AND MUCH
OF SAT NITE...WITH SOME LOW-LVL MSTR ACRS NY STATE LATE ON SUN NITE.
SOME MID-LVL MSTR TO START TO AFFECT THE ST LAW VLY BY LATE TONITE
AND THE ENTIRE FA ON SAT AND EARLY ON SAT NITE. SOME MID-LVL MSTR TO
AFFECT THE FA LATE ON SUN NITE. NAM/GFS/NGM SHOW PW VALUES OF BLO
0.2" ACRS THE FA THROUGHOUT THE SHORT-TERM PERIOD. 12Z NAM/GFS/NGM
QPF ACRS THE FA THRU 12Z SUN TO BE AOB 0.1". WWE SN GRAPHICS SHOW AOB
AN INCH ACRS THE FA ON DAYS 1 AND 3...AND AOB 2" ON DAY 2.

WITH WINDS EXPECTED TO DIE OFF EARLY THIS EVENING ACRS THE FA...WILL
LET THE GOING WIND CHILL HEADLINES EXPIRE WITH THIS PACKAGE. LATEST
NAM BUFR DATA SHOWS THE CONTINUING POTNL FOR LK EFFECT CLDS OFF LK
CHAMP INTO TONITE. SOME MORE CLDS TO START TO IMPACT THE WRN FA BY
LATER TONITE...THEN CLDS EXPECTED TO INCREASE ACRS THE FA ON SAT.
THERE/S STILL THE OUTSIDE CHC FOR SOME -SN BEFORE EVENING ON SAT...SO
WILL CONT SOME LOW CHC POPS FOR THEN. WILL CONT TO CARRY THE HIGHEST
POPS (LIKELY FOR NOW) ACRS SRN VT ON SAT NITE...WHERE AOB ADVISORY
CRITERIA (4") SNOWFALL MAY OCCUR. DRY WX...WITH A DECREASE IN CLDS
DURING THE DAY ON SUN AND MORE CLDS RETURNING BY LATER ON SUN NITE...
STILL LOOKS GOOD FOR THE REST OF THE SHORT-TERM PERIOD.

WRK ZONES AND PRELIM ISC GRIDS AVAILABLE. ALL FINAL PRODUCTS BY
AROUND 4 PM.

MURRAY

.LONG TERM (MON ONWARD)...
A GRADUAL TRANSITION TO MILDER THAN NORMAL WEATHER WILL OCCUR BY
MIDWEEK. ANY STORMS WILL BE WEAK AND NOT PRODUCE MUCH PRECIPITATION.
THERE IS A CHANCE THAT SOME RAIN SHOWERS MAY MIX IN WITH SHSN LATE
WEDNESDAY...BUT THE RETURN TO SLIGHTLY COOLER WEATHER THURSDAY AND
FRIDAY WILL PROBABLY PRODUCE SOME LIGHT SNOW AGAIN.

AFTER THE BIG STORM OFF THE NEW ENGLAND COAST MOVES TOWARD
NEWFOUNDLAND ON SUNDAY NIGHT...THE NEXT FEATURE WILL BE A WEAK
CLIPPER MOVING SEWRD FROM THE NRN LAKES TOWARD NEW ENGLAND. CHANNELED
VORTICITY MAY PRODUCE A NARROW STRIPE OF STRONG VERTICAL MOTION
MAINLY TO THE SOUTH OF US...BUT SFC MSTR CNVGC AND OVRRNG ARE
WEAKENING...SO ANY SNOW ACCUMULATIONS SHOULD BE QUITE LIGHT MONDAY
EVENING.

TUESDAY SHOULD BE DRYING OUT WITH A WEAK RIDGE OF HIGH PRESSURE.
OVRRNG AHEAD OF THE NEXT STRONGER S/WV IN THE NORTHWEST FLOW COULD
BRING SOME LIGHT SNOW OR RAIN SHOWERS WED AND WED NGT...AS MILDER
WEATHER ARRIVES WITH THE SFC LOW TRACKING NORTH OF THE FORECAST
AREA.

BY THURSDAY AND FRIDAY...FORECAST MODELS BECOME INCONSISTENT ON ANY
ADDITIONAL S/WVS THAT MAY SLOW AND RE-DEEPEN THE LONG WAVE TROF ALONG
THE NEW ENGLAND COAST. COOLER WITH A CHANCE OF SNOW OR SNOW SHOWERS
SEEMS THE FORECAST OF LEAST REGRET AT THIS TIME.

REB

.AVIATION...
NO SIGNIFICANT WEATHER EXPECTED FOR THE NEXT 24 HOURS THAT WILL
IMPACT AVIATION. LOOK FOR CLEAR SKIES AND LIGHT WINDS ACROSS THE AREA
TONIGHT WITH MID LEVEL CLOUDS INCREASING FROM WEST TO EAST BEGINNING
AFTER 12Z SATURDAY.
